Man in the Arena
"It is not the critic who counts: not the man who points out how the strong man
stumbles or where the doer of deeds could have done better. The credit belongs to
the man who is actually in the arena, whose face is marred by dust and sweat

Nonlinear equations: Newton-Raphson

Introduction
Our topic here is solving for the roots of nonlinear equations, i.e. for the values of a single
variable, x, that renders the nonlinear function f (x) = 0; later we will deal with simultaneous
nonlinear e

Nonlinear Ordinary differential Equations

Preface
These notes are concerned with establishing some basic procedures for integrating nonlinear
ordinary differential equations. In particular, we are interested in what are known as initial
value problems w

Introduction
Consider a taut string under continuous tensile force T as shown in Fig. 1;
gravitational forces will be ignored as they are assumed to be small compared
to the other forces involved. Given the coordinate system sh

Mathematical Preliminaries: Part I
Consider a vector, u,1 referenced to a base system consisting of unit orthonormal vectors. Let these vectors be i, j, k and let them be aligned along the

The Inverse of a Non-singular Lower Triangular Matrix
Introduction & Background
Here we develop an algorithm for computing the inverse of a non-singular lower triangular
matrix, L; call the inverse to L, L1 . The elements of L will be `ij and of

Preface and logic
Evaluating large polynomials can be quite computationally expensive and so an efficient
scheme for evaluating them and their derivatives is, in itself, quite useful. Moreover, if one
